Testimonials

Kind words from our customers:

  • “GWY’s parts inventory and response is top notch. You can expect prompt, respectful, knowledgeable answers to questions and full cooperation when you need it. Truly a mark of a reputable company with a good team.”

  • “GWY has been a great company to work with. My company requires receipts for all credit card purchases and GWY has made this very easy. With rental equipment this usually isn't the easiest to deal with but they have made this process very smooth. I get a weekly receipt emailed to me without having to ask for it. They also have great customer service and are very helpful and friendly. Would definitely recommend.”

FAQs

Because the TN-tool is rotation based, can it do smaller sizes than what it is recommended for?

No, because for the tool to start counting the degrees of rotation, a certain torque must be met.

Does my TN wrench need to be calibrated?

No, Turn-of-Nut (TN) wrenches do not require calibration. TN tools are rotation tools and measure rotation mechanically. These tools either work or they do not. You can match mark to show they are functioning properly.

Are the same size sockets interchangeable between different tools?

Typically, the answer is no but there are exceptions. Contact a specialist if you have specific questions about your tool socket size.
